GERMANY. a is PROCESS OF'MAKING ARTIFICIAL MUSK.

'SPElGlFICATION forming part of Letters Patent No. 412, 545, dated. October 8, 1889.

To all whom, it may concern;

Be it known that we, EMIL SCHNAUFER and HEINRICH HUPEELD, both subjects of the Emperor of Germany, residing at Frankforton-the-Main, Germany, have invented new and useful Improvements in- Art-ificialMusk,--

of which the following s a specification.-

This invention relates-t0 the manufacture ofa substitute for musk.

7 To produce thisartificial substitute, heat three kilograms of metaxylol with two kil0- grams of isobutylalcohol and-nine kilograms of chloride of zinc, in a digester, to from 220 Y to 240 Celsius, until the pressure, which at 5 twenty-nine atmospheres, sinks to below six atmospheres.

is-from five to eight days. ,The resuiting hy- .the commencement is from twenty-five to The duration of the operation drocarbomcorresponding to the formula O H 5, is'collected, and thefraction which distills overat from 190 to 2 3 0--is nitrated with EH0 or with HNOQand H 80 while being -cooled.. The productof the reactionis pouredv into water, whereupon a. reddish-brown oil Application filed February 11. 1889. Serial No. 299,507. (No specimens.)

separates out, which is washed several times with alkaline water. The formula of this oil is O l-1 N0 and in a concentrated condition it possesses a sweet smell, while in a-dilute solution it gives 0d a penetrating and endurin-g-musk-like odor. Y I

We claim as new and desire to secure :by Letters Patentg v The herein-described process of making an oil adapted to be used as a substitute for musk, which consists in digestinga mixture 'of -metaxylol andis'obutylalcohol with chloride oi zinc,-in nitrating the resulting hydrocarbon, and. in separating the oil therefrom by dissolving out extraneous matter, substantially as herein set forth.

In testimony whereof we have signed our names tothis specification in the presence of two subscribing witnesses.-
